Application April 24, 1947, Serial No. 743,608 a 4 Claims. 1

The present invention relates generally to the class of valves, and morespecifically to an improved water supply protector and regulator ormulti-valve appliance, which, while well adapted for controlling theflow of fluids under pressure, is especially designed as a protectiveelement for installation in water supply pipes in connection withdomestic and'other water pressure systems. By the installation andutilization of the appliance of my invention back pressure or drainagefrom a supplied system to a water main is prevented, thus eliminatingpossibility of contamination of the main water supply; a water lockwithin the appliance is prevented; and means are provided fordischargingexcess or waste water from a supplied system, Without interference withthe free flow of water from the water main to the supplied system. Whileconstantly supplying and regulating the flow of water from the watermain to the supplied system, the latter is also automatically protectedby the appliance from any' excessive pressure in the Water main.

The valved appliance of my invention is composed of a minimum number ofstandardized parts that with facility and low cost of produc tion may bemanufacturedand the component parts may be assembled with facility, toprovide a durable, reliable, and efiicient water -pipe fitting which maybe installed with ease and dispatch.

The invention consists in certain novel features of construction andcombinations and arrangements of parts involving a valve casing andmultiple interior hinged and suspended valves actuated under fluidpressure, as will hereinafter be described and more particularly pointedout in the appended claims.

In the accompanying drawings I have illustrated one complete example ofa physical embodiment of my invention in which the component parts arecombined and arranged in accord with a mode I have devised for thepractical application of the principles of my invention. It will howeverbe understood that changes and alterations are contemplated and may bemade in these exemplifying drawings and mechanical structures, withinthe scope of my claims, without departing from the principles of theinvention.

Figure 1 is a vertical longitudinal sectional view of an appliance inwhich my invention is embodied; and

Figure 2 is a transverse vertical sectional view, as at line 2-2 of Fig.1.

In the assembly view I utilize a cast metal fitting or valve casing l,preferabl formed with flattened side walls, and an upper inclined frontwall fashioned with an exterior threaded flange 2 surrounding an openingand normally closed by a removable assembly cap or plug 3, which permitsaccess to the interior of the casing for assembling the interioroperating parts of the ap pli-ance.

The interior of the casing is divided by an integral verticaltransversely arranged partition 4 to form at one side an intake chamberfor water under pressure to be supplied through a supply pipe 5 at thefront or outer side of the casing; and at the inner or rear side ofupright partition, an integral horizontal partition 6 forms a wastedischarge chamber having an outlet or waste pipe I and an outlet ordelivery chamber opening to a delivery pipe 8 that is alined with theintake pipe 5, and of the same capacity and diameter for supplying waterto the water system of whic the appliance forms a part. For controllinthe supply of water from. the

intake pipe to the delivery oroutlet pipe, and ior regulating thedischarge of waste water as well as for relieving excessive fluidpressure within the valve casing, I provide multiple valves of thehinged and suspended flap type which are an ranged to open and closeports under fluid pressure, and a lower intake port 9 of the casing fromthe supply pipe or inlet pipe 5 is controlled by valve Ill, This one-wayor check valve, which opens inwardly under fluid pressure is in the formof a circular disk that is pivotally suspended on pin II that is mountedupon the interior face of the wall of the intake chamber. The valvestructure includes a vertically disposed arm 12 that is secured by studbolt 13 andnut M to the disk It, and the valve under fluid pressurefromthe water main is adapted to swing inwardly on its pinto open positionfor flow of water into the intake chamber; the opening movement of thevalve being limited by means of a Stop. lug I5 on the lower end of thearm l2;

From the intake chamber water under pressure is adapted to flow througha circular outlet 'port or passage l6 into the outlet chamber, andthence through the outlet pipe 8 to the water system being supplied withwater. For controlling the ilow of water through the port or passage Ita hinged disk valve I1 is located in the delivery chamber and adapted toopen outwardly, and the valve is mounted on an arm l8 that is pivotallysuspended on pin l9. This delivery valve, it will be seen in pivotallymounted upon a comparatively large differential and back pressure valve20 located in the intake chamber, for controlling a larger port 2| inthe upright partition 4, and the outlet valve I! when closed is locatedin this large port,

The back pressure valve 20 is provided with a tubular boss that formsthe port or passage 16 for the outlet or delivery valve l1 and the bosspasses through a long arm 22 of the differential valve and is securedthereto by lock nut 23, and the arm is suspended to swing with the valveon a pivot pin 24 mounted in supporting ears near the top of. theupright partition 4i 1 I For discharging waste water from the intakechamber the inwardly opening differential valve is equipped with ahinged and suspended dis a charge valve 25 that normally closes theinner:

port of a passage 26 in the upper portion of the upright partition 4,and as ShOWn valve 2 5 that is located in the intake chamber, swings toopen position with the differential valve 20, under back pressure fromthe water system.

Valve 20 and valve 25, are rigidly attached to thelongarm and valve 210,which is arranged eccentricallyof the delivery valve ll, isprovideclwitha centering pin. P that passes through a hole bored in the arm 22 foruse in assemblingthe parts.

At the Waste discharge side of the partition 4 the outlet port of thepassage 2-6 is controlled by another hinged valve 21 that is suspendedin the discharge chamber on pivot pin 28, and the opening movement ofthis check valve or one-way valve is governed or regulated by means of aset screw 29 threaded through a bore in the upper wall of the valvecasing. The set screw projects into the path of movement of a stopv lug30 Of the valve 21 and a spring 3 I is provided to afford a resilientpressure against thev lug. By means of the spring and set screw the,opening of the valve 21: may be regulated for a predetermined backpressure in the casing.

From this description taken in connection with the drawings it will beevident that when the valve I0 is opened under fluid pressure from thewater main, water flows into the intake chamber, closing thedifieren-tial whack-pressure valve 204 and the discharge valve 25, andopening the delivery valve I! for passage of water through the deliverychamber into the pipe 8.

To prevent back drainage from the, water system through the valve casingto the wate main that might contaminate the water in the main,

and to relieve any excessive back pressure from the water system in caseof a negative pressure o'nthe intake valve 10,,if andwhen th e fluidpressure in the delivery chamber is sufficient to open valve 211, theintake valve it is closed. The swing. ing, movement of arm 22 of theba-c-kpressure valve also opens the discharge valve '25. to flow of"excess water through port 26, thereby opening the waste valve 21 fordisposal of excess pressure through the drainage pipe 1.

Having thus fully described my invention, what I claim as new and desiretfo secure by Letters Patent is:

:vertical integral partition and a closed, horizontal partition formingan intake chamber, a delivery chamber and adischarge chamber, of apivotally -suspended valve openin into the intake chamber, of anoutwardly opening delivery valve in the delivery chamber, means fortrapping excess back-pressure fluid in the intake chamber, and means.for draining said, back; pressure fluid; into the discharge chamber.
